title: Expression and Purification of Secreted Forms of HSV Glycoproteins from Baculovirus-Infected Insect Cells.
abstract: Herpes simplex virus (HSV) remains a major human pathogen worldwide (25 causing cold sores, eye and genital infections, blindness, encephalitis, and neonatal infections. Most adults have antibodies against the oral form of the virus HSV-1 (9), and a significant number are infected with the genital form, HSV-2. Both serotypes establish lifelong latent infections and reactivate periodically to produce recurrent disease (25). After infection, virus-encoded glycoproteins are expressed on all cellular membranes and are major targets of the host's immune response. The virion envelope contains 10 glycoproteins that are important for infection and pathogenesis of HSV-1 and HSV-2. Because HSV contains so many glycoproteins, sorting out their functions in virus entry remains a difficult task. Our approach has focused on establishing structure-function relationships of the individual glycoproteins with particular emphasis on gC and gD. After many years of studying the properties of these proteins in HSV-infected and plasmid-transfected mammalian cells, we have now begun to overexpress the proteins using a baculovirus expression system.
